As an American, I can tell you as fact that it will be a long time...the majority of kids just don’t play it past 12yrs old. There’s ‘soccer fields’ everywhere over here, and it’s mostly girls or young boys...when they get to high school age, they switch over to more mainstream sports. The mainstream sports fans in the USA
cannot stand the falling over and feigning injury everytime a player comes near them...when I say cannot stand it, I mean my older brother telling me to “turn this fuckin shit off” (PL matches) everytime we watch sports together

I think the world is safe for the foreseeable future.
